Abstract

An optical connection between an optoelectronic structural element and a fiber-optic beam waveguide is described which is reliable, simple, and space-saving. A lens and a hollow cylinder are integrated in the structural component of optoelectronic structural elements. Each end of a fiber-optic beam waveguide is inserted into the hollow cylinders, and the optoelectronic structural elements are connected with the aid of a heat-shrinkable tubing with the fiber-optic beam waveguide such that the ends of the light beam waveguide to be coupled abut each of the lens integrated into the optoelectronic structural elements. An optocoupler according to the invention may be advantageously used in motor vehicles, in electromedicine, in power electronics, in robot control, in sensory analysis, and in "instrumentaion-control-regulation" tasks.
